User manual

You can search silently or at any level of
constant sound. It is recommended that
you always operate the instrument at a
minimum level of audible sound. You can
hear the audio increase sharply when-
ever a desirable target is encountered.
(Remember, a cursor will indicate every
target.) When headphones are used, it
will usually be necessary to decrease the
threshold level since sound is more audible
through headphones.
Frequency
This detector is capable of operating at
eight different detection frequencies or
channels, which you will find valuable if
you participate in competition hunting or
if you enjoy hunting with others. In fact,
operating your GTI 2500 at a different fre-
quency might be necessary any time two
or more detectors are being used so close
